New recruit Scott can't wait to lock up some bad guys. Fresh out of police training college, he is a little frustrated to be puppy-walked by a female officer. Not that Scott is sexist or a misogynist (he loves his girlfriend and adores his mum), it's just that he craves the company and approval of other guys. He also suffers from White Knight syndrome and has a tendency to see women as damsels in distress. You see, when Scott was twelve, his dad died saving a family in a horrific motorway crash. It's a legend that Scott is desperate to live up to.
The last thing Nisha needs is a White Knight - and she's the total opposite of a damsel in distress. The experienced beat cop has been there, done that and received a commendation for bravery. She's charmed by Scott's boyish enthusiasm, he's a good-hearted soul, and she decides not to burst his balloon - he can find out the hard way that the job is much more about dealing with the sick and the vulnerable than tackling armed robbers.
Nisha joined the police because she thought the job would suit her - she's always had an enquiring mind and she likes dealing with people - but also because, after Stephen Lawrence, she felt that the Metropolitan Police needed people like her. She has faced hostility from friends and family but she's stuck to her guns.
What Nisha doesn't know is that tonight is a night she'll never forget. Because, while Scott and Nisha are - among other things - dealing with a paranoid schizophrenic teen who may have stolen a dog, a group of people are climbing into a van in a London suburb. And they're planning mass murder.
It all feels rather formulaic and one just knows that there will be further series featuring these two.
